<html><body> I originally sent this to Carl and he kindly suggested I re-post it to this mailing list, so... I have been working on some bugs in the Mozilla SVG arena. The initial stroke-cap is missing from the very first dash-array element drawn in the following svg example. I noticed there was a cairo bug already in the system, <a href="https://bugs.freedesktop.org/show_bug.cgi?id=4409">https://bugs.freedesktop.org/show_bug.cgi?id=4409</a>, that addressed this issue, or close to it, but apparently still exists on, at least, the Windows XP version of recent builds of firefox. I don't think this has been resolved in the most recent version of cairo-path-stroke.c. This is the svg example I have been playing with that shows this problem: <?xml version="1.0" ?> <svg xmlns="<a href="http://www.w3.org/2000/svg">http://www.w3.org/2000/svg</a>" viewBox="0 0 600 600"> <rect x="20" y="20" width="100" height="100" fill="blue" stroke="red" stroke-width="20" stroke-dasharray="0.001,20" stroke-linecap="round"/> </svg> If you render this in firefox, you will notice that the very first leading cap is cutoff. I am using a recent mozilla/gfx/cairo/cairo/src/cairo-path-stroke.c file from the Mozilla core to make changes for testing so my cvs diff is off from the cairo base code (otherwise I would include the entire patch). This change is minor but makes a difference in the rendering of the first array element in the case above. Here is a fix for it: @@ -720,21 +738,20 @@ _cairo_stroker_line_to_dashed (void *clo if (stroker->has_current_face) { status = _cairo_stroker_join (stroker, &stroker->current_face, &sub_start); if (status) return status; } else { if (!stroker->has_first_face) { stroker->first_face = sub_start; stroker->has_first_face = 1; - } else { + } status = _cairo_stroker_add_leading_cap (stroker, &sub_start); if (status) return status; - } } } if (remain) { /* * Cap if not at end of segment */ status = _cairo_stroker_add_trailing_cap (stroker, &sub_end); if (status) The problem with the above svg example is that the first element in this dash-array NEVER invokes _cairo_stroker_add_leading_cap. I think _cairo_stroker_add_leading_cap needs to be called in both cases of if (!stroker->has_first_face). Thanks, Keith</body></html>
